Combined electric probe and processing method for high-speed moving metal flyer test

Abstract

The invention discloses a combined type electric probe for testing a high-speed moved metal flyer. Multiple metal wires are distributed on the circumferential wall of an adhesive-film cylinder evenly, the front ends of different mental wires are not aligned and form multiple steps together with the front end of an adhesive film, a fixing cylinder is located on the rear section inside the adhesive-film cylinder and is connected with the adhesive-film cylinder mutually, the front end of the fixing cylinder is more closer to the rear end of the adhesive-film cylinder than the front ends of all the metal wires. The invention further discloses a machining method of the combined type electric probe. The method comprises the steps of manufacturing an adhesive-film plate with the mental wires, carrying pressing and solidification, carrying out and a step cutting and finishing, carrying out leading wire numbering, manufacturing a fixing upright, manufacturing the adhesive-film cylinder with the metal wires, bonding and solidifying the fixing upright and obtaining the finished combined type electric probe after checking and packaging. The combined type electric probe is adopted for experiment, experiment data which can only be obtained through multiple times of experiments traditional can be obtained in one time experiment, research cost is lowered obviously, and research period is shortened.

Description

technical field [0001] The invention relates to an electric probe and a processing method in the field of sensors for shock wave physics and detonation physics testing, a combined electric probe and a processing method for testing high-speed moving metal flyers. Background technique [0002] In the field of basic research such as the detonation performance of explosives and the high-pressure physical properties of materials under shock compression, the motion state of flyers is the basic measurement object to characterize the working ability of explosives and the high-pressure physical properties of metal materials; during the development of warheads , the detonation work of explosives to drive the movement of metal flyers is an important feature that characterizes product design performance, reflecting the product's killing effect, armor-piercing ability, and convergence compression degree. Evidence on whether the performance of the product deteriorates after long-term stor...

Problems solved by technology

The use of the original electrical probes will bring two adverse consequences: one is that due to the larger diameter of the probes, denser electrical probes cannot be arranged under the flyer, but due to the particularity of the warhead design, the The flyer driven by the boom will have a large deformation during the movement process, and the probes with too large spacing cannot fully reflect the deformation of the flyer; second, the design of the warhead needs to understand the behavior of a certain position on the flyer. The interference between the needles is serious, and it is impossible to bundle a single probe together for use, so it is impossible to continuously measure the continuous motion behavior of a certain position on the flyer. Multiple detonation experiments are necessary to obtain the data of the continuous motion of the flyer. Increased research and development costs and experimental costs
